Fixes for php8.0.0beta3 (#608)

* Set $errcontext argument optional to support PHP 8

- Argument is optional and deprecated in PHP 7.2

* Getting ready for PHP8, handling changed error levels/handlers mostly

* php5 compat syntax

* Updated UndefinedTemplateVarTest for PHP8 (and disabled a check for PHP<5.6) and re-enabled php:nightly in travis config

* Attempt to fix travis runs for (almost) all php versions supported

* Fix unit tests for php8, force composer to think we are still php7 to pick a supported phpunit and being less specific about an error msg because PHP8 is in active development and the exact wording is changing.

* Fixed a unit test that accidentally passed on phpunit < 7 because of sloppy string comparison.

* changelog

* run travis in xenial where possible for latest php versions. Fix unit tests from freakingo over inconsistent error messages in php8-beta.

* Incorporated AnrDaemons suggestions, making composer figure out the required phpunit version instead of specifying it explicitly and removing a unneeded error supression (@).
